The influence of inorg. anions (NO-3, I-, Br-, Cl-, SO42-, and S2O32-) and divalent cations (Ca2+ and Mg2+) on the zeta potential and isoelec. point of α-alumina in aq. medium has been studied. The effect of the anions is highly ion specific even at salt concns. as low as 5 × 10-4 M. This unexpected finding is in line with a recent report. It is also in agreement with an earlier theor. ...
